Doctor of Philosophy / Department of Counseling and Educational Psychology / Fred O. Bradley / The purpose of the current study was to identify if any significant relationships between inspiration, temperament, and positive affect existed. The dependent variable was inspiration, which was measured by the Inspiration Scale (IS). Temperament was measured by the Keirsey Temperament Sorter II and positive affect by the Positive and Negative Affect Schedule (PANAS). One hundred forty-five students attending a large Midwestern university and small community college participated. Initially, participants completed the Keirsey Temperament Sorter II online. The IS and PANAS were administered in the student’s classroom. The data were consequently analyzed to determine if there was a correlation between inspiration and temperament, inspiration and positive affect, and inspiration and the combined effects of temperament and positive affect. The results were mixed: 1. No relationship between inspiration and temperament was discovered. ANOVA results indicated that mean inspiration scores for each temperament did not vary significantly. 2. A relationship was identified between inspiration and positive affect. Regression results suggested a positive linear relationship between inspiration and positive affect scores. 3. When inspiration was correlated with positive affect and temperament combined, no relationship was discovered. A 2 x 4 ANOVA showed no correlation between the variables. The implications these results have on psychology and counseling are discussed, along recommendations for future research. Additionally, limitations of the study, such as inherent risks associated with using self-report measures, are mentioned. The study concludes with a discussion of how future research can investigate inspiration, temperament, and positive affect.

Master of Science / Department of Psychology / Donald A. Saucier / Researchers have yet to examine how trait sensation seeking and state positive affect combine to influence participation in risky behaviors. This study examined how participant levels of sensation seeking and positive affect interacted to influence participant interest in performing a risky behavior. It was hypothesized that an interaction between sensation seeking and positive affect would be found, such that high sensation seekers low in positive affect would show more interest in participating in a risky activity than high sensation seekers that were high in positive affect or all participants low in sensation seeking, regardless of positive affect. Trait sensation seeking was measured in an initial group of participants (N = 693), using a subscale of the Zuckerman-Kuhlman Personality Questionnaire (Zuckerman Kuhlman, Joireman, Teta, & Kraft, 1993). Using these scores, high and low sensation seekers (N = 99) were invited to a second study, where videos were used to manipulate levels of state positive affect (Hemenover, 2003). Participants were then given a questionnaire to measure interest in participating in a risky drug study. No interaction was found, but a main effect for sensation seeking (Zuckerman, 1971) was discovered, such that high sensation seekers reported more interest in participating in a risky behavior than low sensation seekers. Therefore, it appears that participant interest in risky behaviors was a function of levels of trait sensation seeking. It is possible that problems with data collection or the risk-taking scenario contributed to the inability to support the hypothesis.

Sleep problems are common among college students and are associated with numerous negative outcomes including anxiety, depression, executive dysfunction, and poor academic performance. When sleep is limited, individuals may suffer impaired cognitive capacities, such as reduced memory and difficulty focusing attention. Difficulty with these cognitive functions can result in difficulty disengaging from negative thoughts, thereby contributing to negative mood. Poor sleep contributes to negative mood states, but few studies have examined in what way poor sleep may exacerbate negative mood. The purpose of this study was to examine cognitive factors as explanatory variables between sleep and state affect. Participants were undergraduate students from a university in the Midwest. Participants (N = 150, completed baseline questionnaires and wore an actigraphy watch for one night. They returned to the lab the following day to complete additional self-report measures and a computerized cognitive control task. Participants were primarily female (66.67%, n = 100) and white (67.33%, n = 101). To test the hypothesis that the relationship between sleep and affect is explained by cognitive factors, a path analytic model was fit to the data. It was hypothesized that cognitive factors (i.e., Posner task performance, repetitive negative thinking, and self-report attention control) would explain the relationship between sleep (as measured by objective total sleep time and self-report sleepiness) and state affect. The hypothesized model yielded poor global and local fit to the data. While several direct effects emerged in the model, no indirect effects were statistically significant. The model was re-specified, adding paths where large magnitude correlational residual statistics coincided with statistically significant standardized residual statistics. The final model yielded good global and local fit to the data, with primary modifications being added covariances among control variables (e.g., GAD-7 and PHQ-8 scores) with cognitive factors. Overall, the results of this study indicate that the relationship between sleep and next-day affect is complex and cannot be simply explained by cognitive factors. However, the current study found several significant relationships among study variables, suggesting that sleep, cognitive functioning, and emotion are highly related constructs that warrant further study. Future research should examine alternative models incorporating these constructs to find a comprehensive model with utility that can explain the relationships among these constructs.

Social Anxiety Disorder (SAD) is characterized by excessive concern or fear of negative evaluation in one or more social situations and ranks as one of the most common psychiatric disorders. SAD has also been characterized by significant deficits in social motivation and a lack of reactivity to pleasurable stimuli (i.e., positive affect; [PA]), particularly within social contexts. Recent neuroimaging work has shifted towards examining positively-valenced motivational systems in SAD focused on reward responses to social and nonsocial stimuli. These studies have revealed aberrant reward processing during social reward tasks in individuals with SAD. However, not all individuals with SAD exhibit reward circuitry dysfunction. Therefore, the current study aimed to examine if functional patterns of connectivity in the brain underlie heterogeneity in PA differences in individuals with SAD. Results revealed several functional connectivity strength differences between SAD and control groups within reward regions. Additionally, associations between regions of interest (ROIs)-couplings (i.e., OFC and insula, OFC and subgenual cingulate, insula and cingulate, and cingulate and subgenual cingulate) and diminished PA were present in individuals with SAD, but not controls. Lastly, results demonstrated that individuals with SAD had higher variability in their reward connectivity strength presentations and reports of PA as compared to controls. These results hold significance for the development of interventions for SAD that focus on the enhancement of PA to bolster social reward responsivity. / M.S. / Social Anxiety Disorder (SAD) is a common disorder where individuals experience persistent excessive fear of one or more social situations. Individuals with SAD also tend to show lower social motivation and a lack of reactivity to pleasurable activities/events (referred to broadly as positive affect; [PA]), particularly within social situations. Current work has focused on areas within the brain that are responsible for reward responses, and have indicated that individuals with SAD show different types of reward processing during social reward situations. However, not all individuals with SAD show these same patterns. Therefore, the current study aimed to examine if connections between reward regions in the brain underlie differences in PA differences in individuals with SAD. Results showed several differences between SAD and control groups within reward regions of the brain. Additionally, specific associations between brain regions of interest and low PA were present in individuals with SAD, but not controls. Lastly, results demonstrated that individuals with SAD had higher variability in their connections between reward regions and reports of PA as compared to controls. These results can help inform the development of treatments for SAD that focus on the improving PA in an attempt to increase responsiveness to social rewards.

Social anxiety disorder (SAD) is a debilitating disorder marked by persistent fear of one or more social or performance situations that is associated with poor daily functioning in various areas of life. Most empirically-supported interventions for SAD are based on cognitive behavioral models that focus largely on reducing negative emotions. However, these approaches produce only modest rates of remission, suggesting that core components of SAD may not be sufficiently targeted by current treatments. Recent theoretical models have suggested that diminished sensitivity to reward may be a specific factor related to low positive affect (PA) and by extension social anxiety, yet no research has systematically examined this relationship. Additionally, working memory has been found to activate dopamine synthesis related to reward, however this relation has not been demonstrated in social anxiety. Accordingly, research proposed here sought to characterize PA and working memory, and determine whether reward sensitivity is altered in a self-reported socially anxious sample of 59 young adults. We hypothesized that social anxiety symptomatology would be inversely correlated with the magnitude of reward sensitivity as measured using the Reward Bias Task (RBT). Results within the full sample did not support our hypothesis; however, an unexpected relationship between PA and working memory emerged. Once using conservative data quality procedures, results indicated that the online version of the reward bias task demonstrated promising relationships with depression and working memory. Additionally, after controlling for depression, the restricted sample demonstrated a relationship between reward bias mean and working memory, and SPIN and diminished PA. / M.S. / Social anxiety disorder is related to poor daily functioning in various areas of life, such as school, work, and social functioning, and also increases the risk for depression and substance abuse. Over half of patients with the disorder remain symptomatic after treatment. Low levels of positive emotionality, or positive affect (PA), has been associated with social anxiety. Additionally, individuals with social anxiety are thought to have less reward seeking behaviors, which may be related to their working memory abilities. Our study looked at PA, reward and working memory in a sample of 59 socially anxious young adults. Within our full sample, we found that PA and working memory were related, such that participants with higher levels of PA also had better working memory abilities. Within our restricted sample of 17 socially anxious adults we found that reward seeking behaviors were related to depression and working memory. Additionally, after accounting for depression, reward seeking and working memory were related, and social anxiety symptoms and PA were related.

This study explored the relationship between religiosity, hope, and subjective well-being among a group of 430 participants (28.8% male, 88.4% black, 8.4% white) residing in the Gauteng Province South Africa. The sample consisted of students (n = 210) as well as family members of these students (n = 220). A cross-sectional quantitative survey design was used. Data was gathered using the Adult Trait-hope Scale, a three item measure of religiosity, the Satisfaction with Life Scale (SWLS), and the Positive and Negative Affect Schedule (PANAS). Descriptive statistics were computed in SPSS 22. Following this, correlations between all latent variables were calculated in Mplus Version 7.11, where after latent variable modelling was performed. During this process, an initial measurement model was specified, which was examined for goodness of fit, and compared against two competing measurement models. The best fitting model was then subjected to a process of model development, and subsequently re-specified as a structural model. The fit of this model was again assessed and compared to two competing structural models. Finally, indirect effects between religiosity, hope, and subjective well-being (comprised of positive affect, negative affect, and life satisfaction) were investigated. The results revealed that religiosity was a significant predictor of both agency and pathway hope, and that the strength of this relationship was moderate in the case of agency hope, and weak in the case of pathway hope. In turn, agency hope predicted higher levels of life satisfaction and positive affect, and lowered levels of negative affect. However, with the exception of positive affect (with which it was positively associated), pathway hope was not related to any of the subjective well-being variables, suggesting that it is less significantly associated with subjective well-being than agency hope. The results of the mediation analysis revealed that agency hope acted as a significant mediator of the relationship between religiosity and life satisfaction, positive affect, and negative affect. Pathway hope mediated the relationship between religiosity and positive affect. These results suggest that the elevated levels of subjective well-being often found in relation to religiosity can at least in part be attributed to the fact that religion is associated with elevated levels of hope. The mini-dissertation is concluded with a chapter that outlines the conclusions and limitations related to the study, and on this basis, several recommendations were proposed for future research and practical application of the findings. / MA (Positive Psychology), North-West University, Vaal Triangle Campus, 2014

Literature Review: Anhedonia, the loss of interest or pleasure in usually pleasurable activities, is a core symptom of depression and is associated with a reduction in positive affect (PA). Repetitive negative thought (RNT) is implicated in the development and maintenance of psychiatric disorders. It has been hypothesised that RNT causally contributes to anhedonia. The aim of this review was to explore this relationship to answer two questions: Is there a relationship between RNT and anhedonia? Does RNT causally contribute to anhedonia? Review inclusion criteria were: studies using standardised measures to report a relationship between RNT and anhedonia or reduced PA. Results suggest that cross-sectional and longitudinal studies identify a relationship between RNT and anhedonia. Preliminary evidence from experimental studies shows that RNT causally contributes to anhedonia. Limitations within the field are that anhedonia is rarely measured directly or behaviourally. Future research is warranted to explore the relationship between RNT and anhedonia with a particular focus on direct and behavioural measures of anhedonia. Empirical Paper: It is hypothesised that repetitive negative thought (RNT) causally contributes to anhedonia. There is cross-sectional and longitudinal evidence of this relationship, but it has not previously been investigated directly using experimental methods. In the present study, student participants were randomly assigned to an unresolved goal (RNT) manipulation (n = 43) or resolved goal (control) manipulation (n =41) prior to completing a reward sensitivity task. This task has been reliably found to train a response bias towards the stimuli that is differentially positively reinforced, with both depression and self-reported anhedonia associated with a reduced response bias. The unresolved goal versus resolved goal manipulation was effective, with the unresolved condition producing significantly higher levels of RNT during the reward sensitivity task relative to the resolved condition. Inconsistent with study predictions, there was no significant difference between the conditions on response bias, although there were trend findings, which tentatively suggest that RNT may influence anhedonia. Potential accounts for the null findings and future research are discussed.
